In celebration of Samsung’s newest gidget-gadget release, the Galaxy Note II, the brand held an event last night at Skylight at Moynihan Station and commissioned none other than Kanye West for the show. During his set, the G.O.O.D. Music maestro brought out 2 Chainz to perform “Birthday Song.” The crew at Goodfellamedia were all on it, so here’s a clip courtesy of them. Pictures from the shindig can be viewed here.
